A Supernova Observed Just After It Occurred

When stars complete their lifetimes, they are called supernovae. with glorious explosions We know they are gone. However, this event is very difficult to observe, the probability of catching the last moments of a star in the infinity of space is very low.

With the help of clustered galaxies, an international team was able to measure three times the bright light emitted by a supernova in deep space. The information from these observations is end of stars It will also serve to test theories about

A supernova that even telescopes can’t see

The star itself is located quite far from our planet. At a distance that we cannot view with any telescope, 11.5 billion light years As the last lights of this distant star completed its journey to our planet, it was also a difficult challenge to separate the lights of the star from the lights of all other galaxies.

When he can separate the lights of the star, scientists can see how this celestial body “live and die” managed to reveal. Unusual twists and shifts in incoming light due to fluctuations in gravity managed to reveal the existence of the supernova. This configuration, called the Einstein transition, revealed information about the life of the star.

Examined for eight days flares and light changesshowed that the supernova had cooled considerably in a week. This is shown as a development that will enable us to predict exactly how stars turn into supernovas in the future.

According to the researchers, this star was the same as our Sun before it exploded. 530 times had reached volume. Stars first expand considerably when their nuclear fuel runs out, and then collapse rapidly towards their own cores. After this collapse, they complete their lives with a giant nuclear explosion, a supernova. Thanks to the new observation, this process will be examined in much more detail.

Study, nature was published in the magazine.
